Trivia

• Instant Death is not a debuff. Servants and Enemies have a separate Death Resist stat from Debuff Resist. Effects that prevent debuffs do not prevent instant death.
• Servants and enemies can be defeated from Burn reducing HP to 0.
• As of London update, Curse is now stackable.
• As of Shimosa update, Burn & Poison is now stackable.
• Max HP buff also heals unit.
• Healing received from Max HP buff cannot be reduced by Heal Down debuff, but the buff itself can be blocked.
• Normal healing cannot be blocked, but can be reduced by Heal Down debuff.
• Invincible, Evasion, and Guts cannot stack.
• Effect from Necromancy CE counted as permanent Guts.
• Taunt can cause an enemy Servant's Noble Phantasm to fail to execute, but still use up a full Charge Gauge.
  • Needs confirmation! Sometimes behaves this way and sometimes does not.
